MATTRESS OR CUSHIO N AND HEATING ATTACHMENT THEREFOR.

SPECIFICATION forming part of Letters Patent No. 697,27 a ed p il 1902-Application filed December 2, 1901. Serial No. 84,340. (No model.)

1"0 (1 66 whom it may concern:

Be it known that I, ADOLF G. SoHMIED, a citizen of the United States,residing at Marysville,in the county of Marshall and State of Kansas,have made certain new and useful Improvements in Mattresses or Cushionsand Heating Attachments Therefor, of which the following is aspecification.

It is the object of my invention to provide an improved cushion ormattress and animproved attachment for heating the same for variouspurposes or uses.

The details of construction are as hereinafter described, referencebeing had to the accompanying drawings, in which- Figure l is aperspective View of a mattress provided with my improved heatingappliance, part being broken away to show the interior arrangement. Fig.2 is aplan view of the heating attachment or appliance. Fig. 3 is across-section of the mattress and the heating appliance filled withwater. Fig. 4 is a longitudinal section of a portion of the mattress andheating appliance on the line at 4. of Fig. 1. Fig. 5 is a side viewillustrating an application of my invention.

Since my invention is applicable to cushions as well as mattresses, itwill be understood in the following description reference is made toboth.

The mattress A is made with separable top and bottom portions which areconnected at one side only and provided on the opposite side and at theends with a flap a, which is adapted to be secured by buttons, as shown.The lower half or portion of the mattress A (see Fig. 3) is constructedwith longitudinal raised portions or ribs, which are spaced apartequidistantly and terminate a short dis; tance from the ends of themattress. (See Fig. 1.) The edges of the lower portion of the mattressare likewise provided with ribs a, which are also parallel with themiddle ribs or projections a. It is apparent that spaces or depressionsare left between the projections a and also between them and the edgeprojections or ribs a. These spaces adapt the mattress to receive theheating appliance or attachment B. (Shown best in plan view, Fig. 2.)The same consists of a series of tubes or tubular portions I), havingconnecting transverse tubular heads I), which are provided with nozzleshaving screw-plugs b The longitudinal portions b are adapted to lie inthe spaces provided between the loogitudinal ribs or projections a and aof the mattress, while the heads I) lie in the transverse spaces ordepressions and between the ends of the projections a and the end ribs(L as shown in Fig. 1. The appliance B may be filled or charged with hotwater for the purpose of heating the mattress A. In case the mattress isto be supported fiat or extended, as shown in Fig. 1, the heater B ispreferably constructed of aluminium; but in case the mattress or cushionis to be bent or curved at different anglesas,for example,when a cushionis applied to an invalids chair, as shown in Fig. 5-the heater B isconstructed of rubber. It will be understood that the same constructionadapts the invention for use in carriages or sleighs and in variousother positions or situations Where Warmth is required in a bed orcushion. In such case hot water may be conveniently poured into theholder B by medium of a funnel, as shown in Fig. 5, and the water may bedrawn off from the lower nozzle into a bucket or pail when itis requiredto charge the heater with an additional quantity of hot water. It isobvious that steam or hot air may be applied as a heating medium inplace of water, and it is further apparent that pipes may be connectedwith the nozzles of the heater, as indicated by dotted lines, Fig. 1,for the purpose of circulating hot water, hot air, or steam through thesame. In brief, I propose to apply the heating agent or medium in anyway that may be most convenient or as dictated by conditions, 850.

The longitudinal parts I) of the heater lie in the spaces between theprojections or ribs of the mattress and prevent any displacement of theheater when in use. The arrangement of the tubular portions 1) 0f theheater so that the projections or ribs (1 of the mattress intervene isoften of much advantage in facilitating the application of a greaterdegree of heat to one portion of the body of the occupant than toan0ther,-since he may rest mainly upon that portion of the mattresswhich is directly over the projections a or, if desired, directly uponthe portion lying over one of the tubular parts I) of the heater. Inbrief, the heat may be graduated in its application to the person of theoccupant by the latter shifting his body from one part of the mattressto another, and, further, this arrangement prevents the'water beingpressed from one side to the other, and thus keeps the surface of themattress or cushion level,or nearly so, when subjected to the Weight ofan 0ccu pant, which would not be the case'if the heater were constructedwith a single undivided chamber.

It is obvious that by unbuttoning the flap a at one or both ends of themattress proper the heating appliance B may be readily in sortedorwithdrawn, and for convenience in this respect I provide it with aflexible loop 12 as shown in Fig. 2. 7

Having thus described my invention, what I claim as new, and desire tosecu re by Letters Patent, is

1. A mattress or cushion adapted for receiving a heating appliance, thesame having top and bottom portions which are connected at one side butotherwise separable, one of them being provided interiorly withprojections or ribs, and spaces intervening them for accommodating aheater, substantially as shown and described.

2. An improved mattress or cushion for receiving 'a heating appliance,the same having separable top and bottom portions and intorior ribs orprojections surrounded by spaces which intervene them and the sideportions of the mattress, substantially as shown and described.

3. The improved mattress or cushion having separable top and bottomportions and provided interiorly with lengthwise ribs or projectionsextending parallel and spaced apart from each other and from the sidesand ends of the mattress whereby the latter is adapted to receive aheating appliance having a form corresponding to the spaces surroundingsaid projections, substantially as shown and described.

4. The combination with a mattress or cushion having separable top andbottom portions and provided interiorly with projecting portions whichare spaced apart, of a heater formed of tubular portions which areadapted to fit in the spaces between the said projections of themattress, substantially as shown and described.

5. The combination with the'mattress or cushion having separable top andbottom portions and interior parallel lengthwise projections or ribsformed on the bottom portion which projections are spaced from eachother and from the sides and ends of the mattress, of a heatingappliance consisting of a series of parallel tubes and tubular endportions adjoining the same, the heater as a Whole being adapted to liein the spaces provided between the said projections of the mattress andthe sides and the ends of the latter, as shown and described.

6. The combination with a flexible mattress having divided top andbottom portions and provided interiorly with ribs or projections whichare spaced apart, of a flexible heating appliance composed of a seriesof longitudinal tubular portions and tubular end portions, the latterhaving nozzles which are ac cessible at the ends of the mattress andadapted for application of screw-plugs or circulating-pipes, whereby themattress and its contained heater are adapted for use in the mannerdescribed.
